First developed by Tim Berners-Lee in 1990, HTML is short for HyperText Markup Language. HTML is used to create electronic documents (called pages) that are displayed on the World Wide Web.
HTML stands for hyper-text markup language and is a popular language to create websites with. Think of HTML as another language, just like English or Spanish, which tells the computer how to show and render the website you created.
